I rewrote the data storage part of cfgtool. It now stores all
variables in one file, to avoid wasting storage. The one file
is a binary file, which is not very nice, but it should be a
portable one, assuming 8 bit chars and character sets and so on.
I append the manual page.
It's not a good idea to use this until after Debian
1.2 is released. I'm not going to upload it to master
before that. If you want to play with it, fetch it from
<http://www.iki.fi/liw/programs/>. There's the usual Debian
files. Report bugs directly to me. Thanks.
If someone wants to have a go at writing a user interface
that lets an admin more easily view and modify the variables,
don't hesitate to start now.
NAME
cfgtool - manipulate system configuration variables
SYNOPSIS
cfgtool [--create variable value] [--destroy variable]
[--get variable] [--set variable value] [--get-help vari
able] [--set-help variable helpfile language] [--is-true
variable] [--is-false variable] [--exists variable]
[--lock] [--unlock] [--locked] [--list-all] [--create-all]
[--set-all] [--repository directory] [--init-repository
directory]
DESCRIPTION
cfgtool manages a database of system configuration vari
ables.
This should not be used to configure application type pro
grams. Applications should use their own configuration
file, because cfgtool is not portable.
OPTIONS
--init-repository data-directory lock-direcotry
Create and initialize the repository. The data-
directory is created, the lock-directory must exist
or be the same as the data one.
--get variable
Print value of variable to stdout.
--set variable value
Set value of variable to value The variable must
exist.
--create variable value
Create a new variable and set its initial value.
It is not an error for the variable to exist
already. If it does, nothing happens; the value of
the variable is not changed.
--destroy variable
Destroy a variable.
--set-help variable helpfile language
Set description of variable in some given language.
English is "en". Note that LANG is not obeyed for
this option.
--get-help variable
Output description of variable to stdout. LANG is
obeyed.
--is-true variable
Check whether variable exists and contains the
value "yes". Don't output anything, just set the
exit code.
--is-false variable
Opposite of --is-false: condition is true, if vari
able exists and contains the value "no" (actually,
any value but "yes").
--lock Lock variable repository. This is needed only when
you need to lock the repository over several invo
cations of cfgtool. The repository is locked auto
matically, if it hasn't already been locked, but an
implicit lock is also removed automatically. Avoid
locking the repository for long periods of time.
--unlock
Unlock variable repository.
--locked
The variable repository was locked by an earlier
process, but we own the lock. This prevents creat
ing an implicit lock. If we created an explicit
lock with --lock already, the implicit lock fails
and then the whole operation fails. This must be
the first option, except for --repository, if it
used at all.
--list List all existing variable names, one per line.
--exists variable
Test whether a variable exists.
--list-all
Output octet stream to stdout that contains all
variables in repository.
--create-all
Read octet stream from stdin and create all missing
variables.
--set-all
Read octet stream from stdin and create or set all
variables.
--repository directory
Use directory as the repository, instead of default
location. Must be first.
ENVIRONMENT
LANG Language for help files, when reading them.
Default is "en" for English.
